Status: In Production
OS81118 is available for following applications
• MOST150 Coaxial Networks (MOST150 cPHY)
• MOST150 Optical Networks (MOST150 oPHY)
The OS81118 is a Single Network Port highly integrated Intelligent Network Interface Controller (INIC) for the 150 Mbps MOST Network (MOST150) with support for both optical physical layers (oPHY) and coaxial (coax) physical layers (cPHY) that can efficiently handle audio, video, packet, and control data for infotainment and Advanced Driver Assistance Systems (ADAS).
On cPHY it point to point connections with the support of full-duplex communication. This feature contributes to reduce the total system costs through the reduced number of cables and connectors that are necessary to connect the single devices.
The classic ring topology with dual-simplex communication is supported by oPHY and cPHY.
The OS81118 offers following state-of-the-art industry standards as user interfaces: I2C, Streaming Port, MediaLB, SPI, USB2.0 high speed port. From software side, it is compatible with MOST Linux® Driver,MOST NetServices, and the Microchip’s Unified Centralized Network Stack (UNICENS).
INIC provides encapsulation of all low-level functions necessary to develop a MOST-compliant device, significantly simplifying MOST implementation in a node. Supervision of the application is also provided, including a protection mode that is entered when an application is not present (i.e. start-up) or the External Host Controller (EHC) malfunctions. This protection mode prevents application malfunctions from influencing the integrity of the network and the system.
INIC includes the INIC Software Stack, which provides MOST-compliant real-time behavior. Integration of the INIC Software Stack significantly relieves the EHC from real-time processing tasks.
The INIC makes a MOST device accessible according to the rules of the MOST Specification, even without participation from the External Host Controller (EHC). The INIC provides a message-based interface for control and packet data. Configuration is encapsulated within a Function Block (FBlock INIC), which allows the EHC to manage INIC in the same way as other functions in the system.
